PATENT OFFICE.

OF LYON, FRANCE.

Application filed April 8,

To all whom it may concern Be it known that I, JOSEPH CuoUMEL, a citizen of the French Republic, of Lyon, France, have invented certain new and useful Improvements in Apparatus for Finishing Velvet and other Nap Fabrics, of which the following is a specification.

This invention relates to improvements in apparatus for finishing velvet and other nap fabrics.

The object of the present invention is a machine for the final treatment of velvet and other nap fabrics to raise the nap crushed down by the preceding operations and to give to the fabric the desired stability.

The invention consists in submitting the fabric, which has been previously moistened, to the action of cards which raise the nap, being at the same time heated by a range of gas burners placed below. The fabric is then calendered and submitted to the action of further cards rotating in the opposite direction to the first and also heated by a range of gas burners. According to the nature and the condition of the fabric it can be passed through the machine several times until it presents the aspect and qualities desired.

The invention will be described with reference to the accompanying drawings in which Figure 1 is an elevation of the machine.

Fig. 2 is a plan view of the same.

A frame 1 carries two arms 2, which support a bath 3, containing a liquid for the humidification of the fabric and on which are arranged two rollers 4 and 5. A third roller 6 is arranged near the bottom of the bath 3, and can be employed in cases where the fabric requires to be completely immersed. A pressure roller 7 presses against the roller 5 with a pressure which can be regulated by one or more counterweights 8 attached to levers 9 pivoted at 10 to the arms 2, and on which is supported the roller 7. An aspirator 11, of known type is arranged a short distance above the roller 7, to withdraw any excess of moisture in the fabric. The fabric after passing over the guide roller 12 is passed over a card comprising two rollers 13 .and 14, each having steel teeth. The cylinders 13 and 14 are carried in adjustable bearings mounted in slides 15 and 16 affixed to the frame of the machine and each carrying two small rollers 17 and 18 serving to support the fabric while under Specification of Letters Patent.

the action of the cards. The height of the cylinders 13 and 14, and consequently the pressure exercisedby them on the fabric is re ulated by the screws 19 and 20.

l3elow the nap raising mechanism is situated a gas'furnace 21 heated by a number of burners 22. A calender also heated by gas is arranged after the furnace 21. It is formed by a hollow cylinder 23, with interior burners carried by a lever 24, pivoted at 25 to a sup port 26, the height of which can be adjusted by the screw 27 actuated by the hand wheel 28.

A second card 29, 30 similar to the card 13, 14 but rotating in the opposite direction is carried on the frame 1, behind the calender 23. It is also heated by a gas furnace 31. The fabric is guided around by two rollers 32, 33, the former being carried by two supports 34 and rotated by a toothed wheel 35 gearing with a pinion 36 carried by a shaft on which is keyed a cone 37 around which a belt 38 passes to transmit the motion from an inverse cone 39. The latter is provided with a belt 40 operated from a driving pulley 41 which also actuates the card cylinders 13, 14, 29 and 30.

In the case where'the fabric 42 to be treated is to be passed several times through the machine, its two ends are suitably connected together to form a continuous band resting on the table 43. The fabric first passes over a stretching frame 44 the inclination of which can be varied by a worm wheel 45 actuated by a worm 46 carried on a rod 47 passing through a bearing 48 in the frame 1, and operated by the hand wheel 49. The fabric then passes around two guide rollers 50 and 51, and thence to the rollers 4 and 5, dipping into the bath 3 and if it is desired to entirely immerse the fabric it is passed under the roller 6. The excess of liquid is removed by the pressure between the rollers 5 and 7 and then by the action of the aspirator 11. The fabric is then led in direction parallel to the upper table of the machine and submitted successively to the action of the card cylinders 13, 14, the calender 23 and the card cylinders 29 and 30 which raise the nap and give the fabric the desired appearance. It is finally directed by the rollers 32 and 33 to the table 43 where itis piled up before being again passed through the machine to again undergo the same cycle of operations.

The rollers can be arranged, as in ordinary stretching machines, to stretch the cloth transversely and prevent the, formation of plaits.

This machine carries out automatically for velvet and nap fabrics the work of stentering which has hitherto been largely done by hand under onerous and defective conditions.

What I claim and desire to secure by Le ters Patent of the United States is Apparatus for finishing velvet and nap fabrics comprising a frame, a table, a reservoir containing a liquid for the humidification of the fabric, rollers in the reservoir, a card comprising two cylinders provided with steel teeth, means for regulating the pressure of said cylinders, heating means for the nap rising mechanism, a calender arranged after the heating means and also heated thereby, means for regulating the height of said calender, a second card in rear of the calender and rotating in the opposite direction to the first card, a stretching frame above the table, means for regulating the inclination of said stretching frame, and means for guiding the fabric to the table Where it is piled up, substantially as described.

In witness whereof I aflix my signature. JOSEPH CUGUMEL. Witnesses:
